Senior Research Scientist
My main research area is
wireless sensor networks (WSN). Our latest project is using GPS for very precise relative localization of mobile nodes. My team has developed the first WSN-based countersniper system. An enhanced version is soldier wearable and not only does it localize the shooter very accurately, but it can also tell the caliber and the weapon type. An interesting paper describes the system in detail. The latest version is smartphone-based. Our radio interferometric positioning approach has gained much attention and resulted in the Best Paper Award at the ACM Sensys 2007 conference.
My other focus is Model Integrated Computing. Our latest open source software tool, the
Web-based Generic Modeling Environment is a web- and cloud-based, collaborative, configurable toolkit for creating domain-specific visual modeling and program synthesis environments.
Our time synchronization paper from 2004 received the
Test of Time Award at ACM SenSys. (November 2014). Our poster on
Medical Capsule Robots received the Best Poster Award at ACM SenSys. (November 2014) Benjamin Babjak has successfully defended his Ph.D dissertation. (September 2014)
I received a
Google Research Award to continue our GPS work. (August 2014) Our paper "Accurate Real-Time Relative Localization Using Single-Frequency GPS" was accepted for
SenSys 2014. We will also present a demo of the system. (August 2014) Our shooter localization technology licensed by a small company was
tested in a school. (August 2014)
Our team (Rigved Joshi, Will Hedgecock and I) received an NSF I-Corps award for the Fall 2014 cohort in Austin TX. (July 2014)
Addisu Taddese, one of my Ph.D. students received a prestigious NSF Graduate Research Fellowship. (April 2014)
Two of my students, Will Hedgecock and Sandor Szilvasi, have successfully defended their Ph.D. dissertations. (March 2014)
Mike Fitzpatrick and I received a grant from MathWorks to turn CS 103 into a MOOC. We plan to create the course in the fall and deliver it through Coursera starting in January 2015l. (March, 2014) Our smartphone-based shooter localization system made it to the
top ten research stories of Vanderbilt in 2013. CS 103, the course I teach on introductory programming was featured in the
MathWorks newsletter. (November 2013) I will be the General Chair of Sensys '14 to take place in Memphis.
Our paper, "
High-Accuracy Differential Tracking of Low-Cost GPS Receivers" was nominated for the at Best Paper Award Mobisys '13 (June, 2013). See a short video on the technique. Our smartphone-based shooter localization systems was featured in news outlets across the globe, including
, the CBSNews.com , Times of India Mashable, , Futurity (Australia), and Gizmag Wired's U.K. edition. More on the app here.
